Description

Technical Field

[0001] This utility model mainly relates to the field of liquid-cooled plate testing, specifically to a liquid-cooled plate flow resistance testing device. Background Technology

[0002] In new energy vehicle batteries, liquid cooling plates are generally used to dissipate heat from the battery cells. The liquid cooling plate achieves its heat dissipation effect by circulating a heat dissipation medium through its internal channels and exchanging heat with the battery cells. Therefore, the quality of the internal channel processing of the liquid cooling plate has a significant impact on the heat dissipation effect. As a result, flow channel testing is performed on the liquid cooling plate during its production process.

[0003] In the invention patent application CN202223606147.4, published on April 28, 2023, entitled "A Flow Resistance Testing Fixture for a Liquid Cooling Plate", a connecting pipe is included. One end of the connecting pipe is provided with a first quick-connect fitting for connecting to a chiller. The first quick-connect fitting is provided with a pressure sensing device for detecting the water pressure inside the first quick-connect fitting. The other end of the connecting pipe is provided with a second quick-connect fitting for connecting to a liquid cooling plate. By integrating the first quick-connect fitting, the pressure sensing device, and the second quick-connect fitting on the connecting pipe, this device can be quickly installed and connected to the chiller's water supply pipe and the liquid cooling plate, and can also detect the chiller's supply water pressure, thereby improving the accuracy and convenience of flow resistance testing.

[0004] However, the aforementioned testing device cannot fix the liquid cooling plate in its testing state during the testing process, which can easily lead to instability in the testing structure of the liquid cooling plate under different postures. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a liquid-cooled plate flow resistance testing device to solve the problem that the installation and fixing of the liquid-cooled plate during the testing process can easily lead to instability in the test structure of the liquid-cooled plate under different postures.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a liquid-cooled plate flow resistance testing device, comprising a device housing, a plate clamping groove provided on one side surface of the device housing, a liquid-cooled mounting plate installed inside the plate clamping groove, and a detection mounting groove provided on the top surface of the device housing, wherein a flow resistance detection tube is installed inside the detection mounting groove.

[0009] Furthermore, several plate clamping grooves and liquid-cooled mounting plates are provided, and the liquid-cooled plate for testing is mounted on the surface of the liquid-cooled mounting plate. The liquid-cooled plate for testing is connected to both sides of the flow resistance detection tube, and the liquid-cooled plate is connected to the flow resistance detection tube through a chiller.

[0010] Furthermore, the liquid-cooled mounting plate includes a suspension spring, an upper clamping plate is provided on the lower surface of the suspension spring, a vertical telescopic spring is provided on the lower end of the upper clamping plate, a lower clamping plate is fixedly connected to the lower surface of the vertical telescopic spring, a transverse spring is provided on the surfaces of the lower clamping plate and the upper clamping plate, and a protective pad is provided on the inner surface of the lower clamping plate and the upper clamping plate.

[0011] Furthermore, the lower clamping plate and the upper clamping plate form an elastic structure through vertical telescopic springs. Both the lower clamping plate and the upper clamping plate are composed of two corner blocks, and the corner blocks are connected by a transverse spring to form an elastic structure.

[0012] Furthermore, the flow resistance detection tube includes an inlet hose, a hose connector is provided on the surface of the other end of the inlet hose, a flow tube is provided on one side of the hose connector, a detection chamber is provided on one side of the flow tube, a pressure sensor is provided on the upper surface of the detection chamber, a flow tube is also provided on the other end of the detection chamber, an inlet hose is provided on one side of the flow tube, and a parallel tube is provided on the side of the detection chamber.

[0013] Furthermore, the number of the inlet hose, hose connector, flow pipe, and detection chamber is the same as that of the liquid-cooled mounting plate, and they are connected to each other through parallel pipes. The surface of the parallel pipes is equipped with sealing valves. One end of the inlet hose is connected to the chiller, and the chiller is connected to the water inlet of the liquid-cooled plate.

[0014] 3. Beneficial effects:

[0015] This utility model features a reasonable design. During the flow resistance testing of a liquid-cooled plate, the liquid-cooled plate is aligned between the lower and upper clamping plates of the liquid-cooled mounting plate as required. Four corner blocks formed by the lower and upper clamping plates lower the liquid-cooled plate at its four corners under the action of vertical and horizontal springs. Simultaneously, the inlet hose in the flow resistance testing tube connects to the chiller and then to one end of the liquid-cooled plate. This ensures that the liquid-cooled plate maintains a fixed posture during testing, preventing instability in the flow resistance testing structure caused by the liquid-cooled plate's varying postures.

[0016] Meanwhile, during the testing process, a liquid-cooled plate with a qualified flow resistance value is installed on the surface of the liquid-cooled mounting plate. Under the action of the chiller, the liquid passes through the inlet hose, hose connector, flow pipe and testing chamber in the flow resistance detection tube, and finally enters the interior of the liquid-cooled plate through the inlet hose. Then it enters the chiller for circulation. The flow resistance performance of the liquid-cooled plate is tested by the pressure sensor. Attached Figure Description

Several plate clamping grooves 2 and liquid-cooled mounting plates 3 are provided, and the liquid-cooled plate being tested is mounted on the surface of the liquid-cooled mounting plate 3. The liquid-cooled plate being tested is connected to the flow resistance detection tube 5 on both sides. This device uses the liquid-cooled mounting plate 3 to fix the detection posture of the liquid-cooled plate, avoiding instability in the flow resistance performance detection structure under different postures.

[0027] The liquid-cooled mounting plate 3 includes a suspension spring 301. An upper clamping plate 302 is provided on the lower surface of the suspension spring 301. A vertical telescopic spring 303 is provided on the lower end of the upper clamping plate 302.

[0028] In this embodiment, when performing the flow resistance test on the liquid-cooled plate, the liquid-cooled plate is aligned between the lower clamping plate 304 and the upper clamping plate 302 of the liquid-cooled mounting plate 3 as required. The four corner blocks formed by the lower clamping plate 304 and the upper clamping plate 302 are lowered and clamped at the four corners of the liquid-cooled plate by the action of the vertical extension spring 303 and the horizontal spring 305, respectively. At the same time, the inlet hose 501 in the flow resistance test tube 5 is connected to the chiller and then to one end of the liquid-cooled plate, so that the liquid-cooled plate is in a fixed posture during the test, avoiding the instability of the flow resistance performance test structure under different postures of the liquid-cooled plate.

A sealing valve is installed on the surface of the parallel pipes 507. One end of the inlet hose 501 is connected to a chiller, and the chiller is connected to the water inlet of the liquid-cooled plate.

[0030] In this embodiment, during the testing process, a liquid-cooled plate with a qualified flow resistance value is installed on the surface of the liquid-cooled mounting plate 3. Under the action of the chiller, the liquid passes through the inlet hose 501, hose connector 502, flow pipe 503 and detection chamber 504 in the flow resistance detection tube 5, and finally enters the interior of the liquid-cooled plate through the inlet hose 506. Then it enters the chiller for circulation. The flow resistance performance of the liquid-cooled plate is tested by the pressure sensor 505.
